Five Changes to Radon Requirements for Fannie & Freddie MF Loans

As the effective date draws closer, multifamily lenders and borrowers should get familiar with FHFA's updated radon sampling requirements.

Agency lenders are preparing to implement the new radon testing standards for Fannie Mae and Freddie Mac multifamily loans. The updated policy applies to loan applications received on or after June 30, 2023. Read the Federal Housing Finance Agency’s (FHFA) January announcement regarding the increased sampling requirements here.

Summary of Changes for Fannie Mae and Freddie Mac Seller/Servicers

There are five main changes in the FHFAs updated radon testing policy:

  1. Requires radon testing at multifamily Enterprise-backed properties, regardless of property location, subject to some exemptions and deferrals.​
  2. Increases required testing from 10% of ground floor units to 25% of ground floor units, with no fewer than one test per building.
  3. Allows no more than 15% lost, faulty, inaccessible tests or environmental professional discretion.
  4. Requires the environmental professional or property representative to provide tenant notifications of radon testing (access, sampling condition requirements, etc.)
  5. Provides additional guidance for lenders and environmental consultants on the Enterprises’ radon standards. As part of such guidance, the Enterprises will reinforce the need for compliance with state and local radon laws.

Note that the updated policy continues to allow an environmental professional to manage the radon testing process.

Loans/Areas Not Subject to Testing

Choosing A Qualified Radon Testing Consultant

In addition to the updated standards issued by FHFA, state regulations and license requirements apply. Tracking and applying the various state regulations adds complexity to the testing process. Lenders should verify that their due diligence provider has a complete understanding of federal and state radon regulations, as well as EPA’s ANSI/AARST standards for all building types. In addition to appropriately experienced and licensed technicians, qualified due diligence providers should also be experienced with reporting templates and standards for Freddie Mac and Fannie Mae.
